Claims priority, application Belgium March 6, 1950 6 Claims. (Cl.242-118) Conical or cylindrical perforated dye tubes made of metal orspecially impregnated paper adapted for winding textile threads,intended for bleaching, dyeing and the like yarnsin package are usedsince a long time.

Nowadays, the thread spools or cheese are executed in such a manner thatfthe two ends o the `tube remain free for instance over about l cm.,because in order to avoid the risk of some threads projecting beyond thebase of the conical tube and being damaged during subsequent handling.

When it is desired to bleach or dye conical cheeses they are fitted overa carrier of the treating machine. Such carriers include a three or fourrib spindle or a perforated dye tube allowing the passage of liquidsthrough the superposed package system thus formed. This cheese system orupright column communicates with the openings provided in the doublebottom of the circulation machine.

It is, however, necessary to insert between the successive conicalcheeses an intermediary spacer or inset acting as a packing between saidcheese. 'Ihis spacer is for instance a round corrugated plate providedin its center with an opening adapted to be fitted on the spindle in thesame manner as the cheeses over the machine carrier. The corrugations ofthe inset washer match through one surface the small diameter of aconical dye tube and through its outer surface the larger diameter ofsuch a tube. Without such spacers, the Wider end of one conical dye tubewould engage the cotton threads on the next and risk cutting the latteror staining them through such a localized pressure.

The use of insets leads, however, to a supplementary operation andimplies the drawback that the workman or the apprentice mayinadvertently lay said insets upside down. On the other hand. as theends of said conical tubes may become damaged through Wear, this resultsalso in a lack of iluidtightness between the tubes and the insets.

The present invention has for its object to make such insets unnecessarywhile avoiding the above mentioned drawbacks. To this end, the largerbase of the perforated conical type is provided With an outer thickersectional ange which allows winding the treads up to the extreme end ofthe tube without any risk of the threads projecting beyond the base ofthe perforated tube.

This thickened wall section or ange may be constituted by a ring weldedover the outside of the cone along the periphery o its larger base butit could also be made through other means e. g. by folding the end ofthe cone outwardly.

A further important feature consists in providing, in addition to theouter extra thickness of the tube, an inner ring-shaped flange. whichmay be shaped through stamping to form a ring engaging' the outwardlyfolded end oi the perforated conical dye tube.

Accompanying drawings show by way of example .and by no means in alimiting sense how the invention may be practically executed.

In said drawings,

Fig. l is a perspective View of a conical dye tube according to ourinvention.

Figs. 2 and 3 are a perspective view and a partly torn-01T sectionalView of a modification.

Fig. i diagrammatically shows two supcrposed improved cones.

Fig. 5 relates to a further modification.

Fig. 6 illustrates means for winding thread on the improved conicaltubes.

In Fig. 1, l designates a perforated metal body forming a conical dyetube that is provided, according to the invention, with a flange, ringor extra thickness 2 along its lower edge defining the larger base ofthe cone.

This ange may be constituted by a ring welded to the edge of the conealthough any other suitable means may be used. This ange or extrathickness thus provides means for winding the thread down to the lowerlimit of the perforated body of the conical tube without any risk ofsome threads sliding oir the cone and it is, therefore, possible tosuperpose the conical cheeses over one another in the treating machineWithout an inset being required between them.

In the embodiment disclosed in ligs. 2 and 3, fthe lower edge 'l of thetube I l is bent outwardly and is provided with a flange 2 that is ttedover the bent edge through stamping so as to form the desired extrathickness.

As illustrated in the drawing, the outer ange 2 may be in one with aninner ring or annulus 8 forming an annular ilange along the edge of theconical tube.

Said latter ring 8 should have preferably a breadth of live to ten mm.but it is necessary in all cases that it allow the tubular cones to fit,to a suihcient extent, inside one another when the spools or cheese aresuperposed inside the treating machine. Furthermore, this ring 8 isprovided advantageously with small apertures 9, the number of which isfor instance six, said openings being adapted to further the passage.

upper edge of the perforated 'conical rtube inwardly, as shown at ll inFig. 5, in ordertovr prevent the formation of a cuttingedge and toincrease the resistance of the Stube.

By reason of the presence ofithelinnerL-.at .ring or annulus 8, thelarger end of the cone extends through a much lesser length over the endof the underlying cone. lesser risk of obtaining undyed partsand .thereis also a lesser deformation of the upper end l'.oi the cheese on whichan overlying cone rests directly and uniformly while a more intimatecontact is provided between the superposed cheese positioned f insidethe` machine in :column formation.

Furthermore, .the resistance of Lthemetal conical tubes is `increased.through vthis rvstructure which :forms an important f advantage, fespecially if` one considers that such articles are oftentaken littlefcare of and easlyallowed tozdrop Lto 'the ground.

Finally, the outer ilangefatthe larger end of the .conical tube by nomeans impedes thereplacement of the-latter by a'wooden-or cardboardcone, once -the package vhas vbeen dried, `before delivering the driedpackage lto the customer, when themetal conesfare` once-more, takenintothe operating cycle.

When it is desired -to wind yarn over such perforatedconical tubes,there'is positionedinside thev cone a mandrel of lwood or the like suit-Vable material made of two parts f3 land yIl. -as

illustrated in Fig. 6, :said wparts being screwed or fitted insidecneanotherand -provided leach with an outer angeror .projectingroutwardly.to an extent such as'to lprevent the terminal flange on theconical tube {..fromldamaging `the drumon the spooling means.
